Can the iPhone 5S Produce Sidetone?

I want to buy a telephone headset for my iPhone 5S and I'd like to get one that produces, and lets you control, sidetone. Sidetone is the quality in which you hear your own voice in the earpiece as you speak into the microphone (as on landline telephones). But I'm having trouble finding out if the 5S can produce sidetone and what headsets will let you control it. Help please!
